and'through ya passage 15a is provided with an abutment engaging point 11 so that during the operation of the motor d controlling and feeding mechanisms said piston may remain stationary and said feed cylinder 7 and motor 2 may be fed to- Projecting laterally from the vdrilling to effect feeding bled relation by means of usual side rods 12L in a Well known manner. Fi 1 is a view partially in elevation and handle member 13 is arranged. with its axis at right angles thereto, a valve casing 16 which has a conical bore 17 in which a valve member 18 is rotatably disposed. At the lower end of the member 16 and screwed into the bore of the latter at 19 is a connec- 30 Huid supply 4connection and controlling tion 20 for motive fluid supply, a. strainer At the end of the 21 being arranged between this connection lar view through a modiand the valve member 18. The latter has a hollow bore 22 which communicates, by way lsectional view taken on larged chamber 25 at ertain positions of ply connection s axially of the valve seat 26 surrounds the passage 24. A

tially extending groove so that the valve 29 may be readily forced to closed position. Surrounding the stem 32 is a manual grasping handle 34 which is held at 35 to a boss 36 arranged at the upper end of the valve member 18. It Will be evident that by rotation of the handle portion 34 the valve 18 may be rotated. When air pressure is on, the valve is forced up into the conical bore which causes the valve to resist accidental turning.

The mode of operation of this form of my invention will be readily apparent. When it is desired to operate the drilling mechanism, the operator will bring the same into the desired position and piace the abutment point 1l against some suitable solid support. He will next rotate the handle portion 34 in such manner as to open communication between the groove 28 and the passage 15, and the port 23 and the passage 14. In order to prevent the pressing of the drill with excessive force against the rock during spotting of the hole, the button 33 may be depressed, partially or wholly closing communication between the passage 24 and the passage 27. After the hole is started, by suitably depressing and releasing the push button 33, the valve 29 may be so moved as to control the supply of tiuld to the feeding mechanism through thel port 15 at such rate as to provide any desired force of feed.

In Figures 3 and 4 I have shown another form which my invention may assume in practice. In most particulars this form of my invention closely resembles that )ust described. However, in certain particulars 1t differs therefrom. It will be noted that the end of the valve casing 16 communlcates with the passa e 14 and that the Huid admission takes p ace through a line 20 opening laterally into the interior of a valve member 1,8 so that supply of fluid .to the motor is controlled by the bringing of a port 23 into communication with the line 20 and the flow of Huid through the valve is, so to speak, reversed. The general arrangement of the valve 29 which corresponds to the valve 29 is the same as in the preceding described form of my invention. The connection, however, to the port '15 is somewhat different, the port 27communieating with a passage 37 which extends longitudinally through the wall of the valve casing 16. This passage 37 opens through a passage 38 into communication with the passage 15. In this form of my invention the valve 29 is operated by a lever 4() which is drawn toward a handle 41 extending at right angles to the handle 13v in order to close the valve 29'. A lug 42 on the handle 41 is adapted to enga e a stop 43 on the valve casing 16 when t e valve 18 is in full open position.

It is believed that it is unnecessary to describe the mode of operation of this mechanism other than to say that by rotation of the handle 41 the port 23 is brought into communication with the inlet 20' and the port 27 is brought into communication with the passage 37, While bv operation of the handle 40 the position of the valve 29 may be varied to control the force of the feed.

While I have in this application specifically described two forms which my invention may assume in ractice, it will be understood that these fbrms of the same are shown for purposes of illustration and that the invention may be modified and embodled in other forms without departing from its spirit or the scope of the appended claims.
